2. Compare HEX, RGB and HSL results, including opacity.
3. Copy an individual row or save the complete conversion as TXT or JSON.

Compare translucent red notation

Input and settings

rgb(255 0 0 / 50%)

Result

RGB alpha 0.5; HEX #FF000080

HEX alpha uses 256 levels, so 50% is rounded to its nearest 8-bit value.

Supported input notation

Both short #RGB/#RGBA and long #RRGGBB/#RRGGBBAA forms are accepted. RGB and HSL functions support comma syntax and space/slash syntax. HSL saturation and lightness require percent signs; hue supports degrees, turns or radians.

RGB channels use 0–255 numbers or percentages, and alpha uses 0–1 or 0–100%. Out-of-range values are rejected rather than silently clamped, making an invalid input visible.

Transparency and color-space limits

The checkerboard is a visual aid and is not part of the color value. Moving the native color picker replaces the text with an opaque HEX color; re-enter alpha in the text field if you need transparency.

Channels are converted to 8-bit sRGB integers and HSL display values are rounded. Display P3, Lab, OKLCH, CMYK, spot colors and profile conversion are not supported. An on-screen swatch does not establish an exact print match.
